Kev sib tov yog ib qho ntawm cov kauj ruam tseem ceeb thiab nyuaj tshaj plaws hauv kev ua cov roj hmab. Nws kuj yog ib qho ntawm cov txheej txheem uas feem ntau ua rau muaj kev hloov pauv zoo. Qhov zoo ntawm cov roj hmab sib xyaw ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum ua haujlwm zoo ntawm kev sib tov roj hmab.
Ua ib tug neeg sib tov roj hmab, yuav ua li cas thiaj ua tau zoo ntawm kev sib tov roj hmab? Kuv xav tias ntxiv rau kev kawm txog kev paub txog txhua hom roj hmab, xws li cov yam ntxwv sib tov thiab cov txheej txheem dosing, nws yog ib qho tsim nyog los ua haujlwm hnyav, xav txog, thiab sib tov roj hmab nrog lub siab. Tsuas yog ua li no thiaj li yog ib tug neeg ua roj hmab uas tsim nyog dua.
Yuav kom paub tseeb tias cov roj hmab sib xyaw zoo thaum lub sijhawm sib tov, cov ntsiab lus hauv qab no yuav tsum tau ua:
1. Txhua yam khoom xyaw nrog cov tshuaj me me tab sis muaj txiaj ntsig zoo yuav tsum tau sib xyaw ua ke thiab sib xyaw kom sib npaug, txwv tsis pub nws yuav ua rau cov roj hmab kub hnyiab lossis ua tsis tau siav.
2. Kev sib tov yuav tsum tau ua raws li cov cai ntawm kev sib tov thiab kev pub mis.
3. Lub sijhawm sib tov yuav tsum tau tswj hwm nruj me ntsis, thiab lub sijhawm yuav tsum tsis txhob ntev dhau lossis luv dhau. Tsuas yog ua li no thiaj li lav tau qhov plasticity ntawm cov roj hmab sib xyaw.
4. Tsis txhob muab pov tseg cov pa roj carbon dub thiab cov khoom seem ntau ntau, tab sis siv tag. Thiab ntxuav lub tais.
Tau kawg, muaj ntau yam uas cuam tshuam rau qhov zoo ntawm cov roj hmab sib xyaw. Txawm li cas los xij, cov tsos mob tshwj xeeb yog kev sib xyaw tsis sib xws, kev txau dej khov, kub hnyiab, thiab lwm yam, uas tuaj yeem pom tau los ntawm kev pom.
Kev sib kis tsis sib xws ntawm cov neeg sawv cev sib xyaw Ntxiv rau cov khoom me me ntawm cov neeg sawv cev sib xyaw rau ntawm qhov chaw ntawm cov roj hmab sib xyaw, txiav cov zaj duab xis nrog riam, thiab yuav muaj cov neeg sawv cev sib xyaw ntawm ntau qhov ntau thiab tsawg ntawm qhov seem ntawm cov roj hmab sib xyaw. Cov khoom sib xyaw sib xyaw sib xyaw sib npaug, thiab seem yog du. Yog tias qhov kev sib kis tsis sib xws ntawm cov neeg sawv cev sib xyaw tsis tuaj yeem daws tau tom qab rov ua kom zoo dua, cov roj hmab dov yuav raug pov tseg. Yog li ntawd, lub tshuab sib tov roj hmab yuav tsum ua raws li cov cai ntawm cov txheej txheem thaum lub sijhawm ua haujlwm, thiab qee zaum, coj cov zaj duab xis los ntawm ob qho kawg thiab nruab nrab ntawm lub dov kom saib seb cov neeg sawv cev sib xyaw puas sib npaug.
Yog tias qhov frosting tsis yog teeb meem ntawm kev tsim cov mis, ces nws yog los ntawm qhov kev txiav txim tsis raug ntawm kev noj tshuaj thaum lub sijhawm sib tov, lossis kev sib tov tsis sib xws thiab kev sib sau ua ke ntawm cov neeg sawv cev sib xyaw. Yog li ntawd, nws yog qhov tsim nyog los tswj hwm cov txheej txheem sib tov kom tsis txhob muaj cov xwm txheej zoo li no.
Kub hnyiab yog ib qho teeb meem tseem ceeb tshaj plaws hauv cov txheej txheem sib tov. Tom qab cov roj hmab kub hnyiab, qhov chaw lossis sab hauv muaj cov roj hmab siav uas ywj. Yog tias kub hnyiab me ntsis, nws tuaj yeem daws tau los ntawm txoj kev nyias dhau. Yog tias kub hnyiab loj heev, cov roj hmab yuav raug pov tseg. Los ntawm qhov kev xav ntawm cov txheej txheem, qhov kub hnyiab ntawm cov roj hmab feem ntau cuam tshuam los ntawm qhov kub thiab txias. Yog tias qhov kub ntawm cov roj hmab kub dhau, cov roj hmab nyoos, tus neeg sawv cev vulcanizing thiab accelerator yuav teb thaum lub sijhawm sib tov, uas yog, kub hnyiab. Hauv qab qhov xwm txheej ib txwm muaj, yog tias cov roj hmab ntau dhau thaum sib tov thiab qhov kub ntawm lub menyuam siab dhau, qhov kub ntawm cov roj hmab yuav nce ntxiv, ua rau kub hnyiab. Tau kawg, yog tias cov txheej txheem pub mis tsis raug, kev ntxiv tus neeg sawv cev vulcanizing thiab accelerator tib lub sijhawm kuj yuav yooj yim ua rau kub hnyiab.
Qhov kev hloov pauv ntawm qhov nyuaj kuj yog ib qho tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov roj hmab sib xyaw. Cov sib xyaw ntawm tib qhov nyuaj feem ntau sib xyaw nrog qhov nyuaj sib txawv, thiab qee qhov txawm tias nyob deb heev. Qhov no feem ntau yog vim qhov sib xyaw tsis sib xws ntawm cov roj hmab sib xyaw thiab qhov tsis zoo ntawm cov neeg sawv cev sib xyaw. Tib lub sijhawm, ntxiv tsawg dua lossis ntau dua carbon dub kuj tseem yuav ua rau muaj kev hloov pauv ntawm qhov nyuaj ntawm cov roj hmab sib xyaw. Ntawm qhov tod tes, qhov hnyav tsis raug ntawm cov neeg sawv cev sib xyaw kuj tseem yuav ua rau muaj kev hloov pauv ntawm qhov nyuaj ntawm cov roj hmab sib xyaw. Xws li kev ntxiv ntawm tus neeg sawv cev vulcanizing thiab accelerator carbon dub, qhov nyuaj ntawm cov roj hmab sib xyaw yuav nce. Cov khoom ua kom mos thiab cov roj hmab nyoos raug hnyav ntau dua, thiab cov carbon dub tsawg dua, thiab qhov nyuaj ntawm cov roj hmab sib xyaw ua rau me dua. Yog tias lub sijhawm sib tov ntev dhau, qhov nyuaj ntawm cov roj hmab sib xyaw yuav txo qis. Yog tias lub sijhawm sib tov luv dhau, cov tshuaj yuav tawv. Yog li ntawd, lub sijhawm sib tov yuav tsum tsis txhob ntev dhau lossis luv dhau. Yog tias qhov sib tov ntev dhau, ntxiv rau qhov txo qis ntawm qhov tawv ntawm cov roj hmab, lub zog tensile ntawm cov roj hmab yuav txo qis, qhov ntev ntawm qhov tawg yuav nce ntxiv, thiab qhov kev tiv thaiv kev laus yuav txo qis. Tib lub sijhawm, nws kuj ua rau cov neeg ua haujlwm siv zog ntau dua thiab siv zog ntau dua.
Yog li ntawd, qhov sib tov tsuas yog yuav tsum muaj peev xwm faib cov tshuaj sib xyaw ua ke hauv cov roj hmab sib xyaw, thiab xyuas kom meej tias cov khoom siv lub cev thiab cov khoom siv kho tshuab xav tau thiab cov kev xav tau ntawm calendering, extrusion thiab lwm yam kev ua haujlwm.
Ua ib tug neeg sib tov roj hmab uas tsim nyog, tsis yog tsuas yog muaj lub luag haujlwm zoo xwb, tab sis kuj yuav tsum paub txog ntau yam roj hmab thiab cov khoom siv raw. Uas yog, tsis yog tsuas yog nkag siab txog lawv cov haujlwm thiab cov khoom, tab sis kuj yuav tsum tau hais lawv lub npe yam tsis muaj daim ntawv lo, tshwj xeeb tshaj yog rau cov tshuaj uas muaj cov tsos zoo sib xws. Piv txwv li, magnesium oxide, nitric oxide thiab calcium hydroxide, cov roj carbon dub uas tiv taus kev hnav siab, cov roj carbon dub ceev ceev thiab cov roj carbon dub semi-reinforced, nrog rau cov roj nitrile-18, nitrile-26, nitrile-40 thiab lwm yam.
